Abstract (en)
[origin: EP0819468A1] Alloy catalyst containing cobalt, nickel, tungsten, chromium and optionally copper, iron or manganese, used for the oxidation of impurities in effluent using peracids and/or hydrogen peroxide catalysts, optionally in combination with organic acids and oxygen, is prepared by heating an alloy containing 10-60 mass % cobalt, 5-50 mass % nickel, 5-20 mass % tungsten, 5-25 mass % chromium and optionally upto 25 mass % copper, iron or manganese for 0.05-3 hr at 250-1250[deg]C in an oxygen atmosphere.
